3. Then the DTMs for the individual VEGALOG module cards must

be added to the project tree. These are in this example: VEGA-

LOG CPU, VEGACOM 558, VEGALOG 571 EP.

4. The two DTM types "VEGALOG 571 EP" and "VEGALOG

571 EV" are VEGALOG module cards for connection of digitally

communicating VEGA sensors. This means appropriate sensor

DTMs can be added to these cards. Select the suitable sensor

DTM from the device catalogue and transfer it into the project

window.
If the sensor is already connected, it is possible to search for it

with PACTware. In this case, the VEGALOG 571 DTM must be in

online mode (right mouse key - "Connect"). Then the automatic

search function can be started via the right mouse key - "Add'l

functions - Instrument search".

5.4 Parameter adjustment (synchronized

operation)

With the parameter adjustment in synchronized operation, the DTM

tries to keep the instance data, this means the data stored in the DTM

are always consistent to the device data. To achieve this, always the

complete data set of the device is read out during connection and

copied to the instance data of the DTM. This mode corresponds to the

standard behaviour of the VEGA DTMs.
After the project is created, the parameter adjustment of the instru-

ment can be started. This is done via double click to the requested

DTM in the project window or via the right mouse key by selecting

"Parameter".
In the following procedure, a difference is made between offline and

online mode.
Offline mode

In offline mode, the project can be prepared, created and stored with-

out connected instruments. Later on, in online mode these data can

be transmitted to the instruments ready for operation.
